We introduce LSA, a new, simple and anytime algorithm that aims to minimize the aggregate regret (or the expected number of mis-classified arms). We prove that our algorithm is instance-wise asymptotically optimal. We also provide comprehensive empirical results to demonstrate the algorithm's superior performance over existing algorithms under a variety of different scenarios.","authors_text":"Chao Tao, Jian Peng, Sa\\`ul Blanco, Yuan Zhou","cross_cats":["stat.ML"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2019-05-27T08:51:26Z","title":"Thresholding Bandit with Optimal Aggregate Regret"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1905.11046","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:14988d525c709b9e97302490f16df58e5d7f1234aa4f8746332dc0cf609a641e","target":"record","created_at":"2026-05-17T23:45:03Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"c2db81ea38e50ca1cd19e852cbc2c003c8719e56468e335ab4f73dac66473235","cross_cats_sorted":["stat.ML"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2019-05-27T08:51:26Z","title_canon_sha256":"fd161d266877355d2ed3692498828612335a1d808973655bfcc066b6ad903487"},"schema_version":"1.0","source":{"id":"1905.11046","kind":"arxiv","version":1}},"canonical_sha256":"791de05ca3c75770d175928321f75d20ee47c053fd45d42bc78adaf27cfc1aa5","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"791de05ca3c75770d175928321f75d20ee47c053fd45d42bc78adaf27cfc1aa5","first_computed_at":"2026-05-17T23:45:03.054772Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:45:03.054772Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"RrFloQVydpSQIPE48qA45abikHBhGtNkA18F5QkUMbn3XBdKg7rEhVMDUJm9nsSlACwWNS4EsDSZfMIDCNcvDQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:45:03.055395Z","signed_message":"canonical_sha256_bytes"},"source_id":"1905.11046","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:14988d525c709b9e97302490f16df58e5d7f1234aa4f8746332dc0cf609a641e","sha256:68d830d54193965b7fa6075455e4d75842d6b9b6f4bc31610f0cca43cf1f6cd8"],"state_sha256":"e5e44a4c88462ac256a3730329afcd3893f06545edd396f9748e69825e941f23"}
